Buying Guide: What to Look For in a Gas Mower for Taller Grass
When your lawn gets a bit wild, a standard mower just won’t cut it. You need a machine built for the challenge, and that means paying close attention to a few key features. I’ve learned from experience that tackling taller grass types requires more than just brute force; it’s about smart design and power management. Let’s break down what you should be looking for.
First and foremost is engine power. You want a mower that won’t bog down or stall when it hits thick, overgrown patches. For taller grass, I recommend looking for an engine with at least 190 cc. This gives you the necessary torque to power through without constantly having to slow down or make multiple passes. A bigger engine usually means a heavier machine, but for this specific job, the extra power is non-negotiable.
Next, consider the cutting deck and its adjustability. A wider deck, say 21 inches or more, covers more ground with each pass, which is a huge time-saver. But the real hero for tall grass is the ability to adjust the cutting height. You need a mower that can be set high, often up to 4 inches or more. This lets you take off the top third of the grass in your first pass without scalping the lawn, which is much healthier for the turf. Look for a single-lever height adjustment system; it’s a game-changer for quickly changing settings on the fly.
Don’t overlook the mower’s construction and deck material. A steel deck is generally more durable and robust than a plastic one, which can be important if you’re hitting hidden sticks or debris in overgrown areas. Also, think about the wheels. Larger, rear-wheel drive (RWD) wheels provide better traction and make it easier to push the mower through dense, tall grass. Self-propelled features are fantastic for reducing your effort, especially on uneven or sloped terrain.
Finally, think about the grass disposal system. A powerful rear-bagging system is excellent for collecting a large volume of clippings, which is essential when you’re cutting down a lot of material. However, a robust mulching kit can be just as valuable, as it chops the clippings finely and returns them to the lawn as nutrient-rich fertilizer. Some of the best gas lawn mowers for taller grass types offer a 3-in-1 system (bag, mulch, side-discharge), giving you the flexibility to choose the best method for the current condition of your lawn.
FAQ
What is the best cutting height for tall grass?
You never want to cut more than one-third of the grass blade’s height at a time. If your grass is very tall, set your mower to its highest setting for the first cut. This might mean you’re still leaving the grass longer than you’d like. Then, wait a few days and lower the setting for a second pass. This gradual approach is much less stressful for the grass and prevents shock, which can turn your lawn brown.
Can I use a regular lawn mower for tall grass?
You can try, but I don’t recommend it. A regular mower lacks the engine power, high clearance, and sturdy construction needed. It will likely stall, clog, and struggle immensely, which is frustrating and could even damage the mower. Using one of the dedicated best gas lawn mowers for taller grass types is a safer and more effective solution that will save you time and hassle in the long run.
How often should I mow to prevent grass from getting too tall?
Consistency is key. During the peak growing season, a weekly mowing schedule is usually sufficient to keep your lawn at a manageable height. If you skip a week due to rain or a busy schedule, you might be okay, but letting it go for two weeks or more will often push it into that “tall grass” category where a standard mower struggles.
Is a mulching kit good for tall grass?
It can be, but with a major caveat. Mulching works by repeatedly cutting the grass clippings into tiny pieces. If the grass is too tall and wet, the mower can get overwhelmed, leading to clumping and clogging. For the best results with a mulcher on tall grass, make sure you’re doing that two-step process I mentioned earlier: a high cut first, followed by a lower cut a few days later with the mulcher engaged.
What safety precautions should I take when mowing tall grass?
Tall grass can hide all sorts of hazards. Before you start, I always walk the area and clear it of large sticks, rocks, toys, or dog bones. Wear sturdy closed-toe shoes, long pants, and safety glasses to protect yourself from debris that the mower might kick up. Be extra cautious on slopes, and always be aware of your surroundings, especially if children or pets are nearby.
